If you check the status page, and the node number you are connected to is NOT listed, it is not US.
For a couple of years now, VK3VS, VK7DB and VK7HH have been working on a project to link the countries repeaters without the problems associated with poor audio, limited connections, and "drive by" operators from other countries that connect, listen, hear nothing and then disconnect again.
Australia has so many un-used repeaters that could benefit from cheap IP based linking.
The idea behind it was to use something cheap, readily available and open source software to connect repeaters via the internet, and make it work. 2 Years in the making, it is finally at a stage that can be released to the Amateur population.
Have a look around the site, read the manual, join the forum and join the fun. You dont need a repeater to use the system, it just helps.
All you need is a raspberry pi, a radio and a CM108/CM119 sound card to start. A riser board is coming to make an "out of the box" solution.
Any questions, join the forum and ask. Look at the current nodes in operation, see status.vklink.com.au
The version of VKlink for the Raspberry Pi 3B+ has now been released
VKLink also comes with the chan_voter channel driver. This interfaces with the VOTER (Voice Observing Time Extension for Radio) board or RTCM (Radio Thin Client Module). This was developed by Jim Dixon (SK), WB6NIL in 2011 and is available as a user-assembleable (VOTER) or commercially built module (RTCM).
As there appears to be a number of AllstarLink nodes in VK, We have developed a series of "helper" scripts for those who do not want to upset their AllstarLink configuration, but also want to join into the VKLink network.
These scripts, while will make any Allstarlink node work with the VKLink system, are aimed at the VK AllstarLink users, and our ZL cousins.
A user manual, and the scripts are available here.
